Derivations of the (n, 2, 1)-nilpotent Lie Algebra
2016
In this paper, we study derivations of the (2, n, 1)-nilpotent Lie Algebra
Stiffness-Adaptive Taylor method for the integration of non-stiff and stiff kinetic models
1992
A systematic derivation procedure that greatly facilitates the application of the Taylor method to the integration of kinetic models is developed. In addition, an algorithm that gives the integration step as a function of the required level of accuracy is proposed. Using the Taylor method, application of this algorithm is immediate and largely reduces the integration time. In addition, a new method of integration of kinetic models, whose most important feature is the self-adaptability to the stiffness of the system along the integration process, is developed. This “stiffness-adaptive” Taylor method (SAT method) makes use of several algorithms, combining them to meet the particular requireme…
Los procesos de derivación locucional en el continuum discursivo de la literatua medieval de castigos
2016
Las características formales y estilísticas del género sapiencial se antojan fundamentales para el estudio histórico de la fraseología. Por su brevedad y concisión, por su capacidad de adaptarse lingu?ísticamente a tradiciones literarias que nacen y se desarrollan en contextos culturales muy diversos, las colecciones de sentencias medievales que tuvieron su eclosión en el siglo XIII y que llegaron hasta el siglo XV como consecuencia de un continuum discursivo, se caracterizaron por manifestar un uso locucional bastante nutrido. Esta investigación tiene como principal objetivo caracterizar todas las locuciones prepositivas cuyo núcleo se vio sometido a un proceso de derivación léxica, lo cua…
Unbounded derivations and *-automorphisms groups of Banach quasi *-algebras
2018
This paper is devoted to the study of unbounded derivations on Banach quasi *-algebras with a particular emphasis to the case when they are infinitesimal generators of one parameter automorphisms groups. Both of them, derivations and automorphisms are considered in a weak sense; i.e., with the use of a certain families of bounded sesquilinear forms. Conditions for a weak *-derivation to be the generator of a *-automorphisms group are given.

O pewnej możliwości porównawczych badań nad słownikami
2016
In the Polish lexicography, there have appeared newer types of dictionaries, including the ones derived from or modelled on earlier lexicographic works. Their evaluation reąuires that objective criteria for a comparative description of dictionaries be developed. In this paper, the author argues that a dictionary constitutes a specific narration (meta-expression) about language reality, and that is why it should be possible to explore any dictionary using a framework modelling all and any expressions produced by language users. Referred to as a “pragmatic frame”, such framework encompasses nine components: who - when - where - about what - in what way - for what purpose one addresses whom - …
A version of Hake’s theorem for Kurzweil–Henstock integral in terms of variational measure
2019
Abstract We introduce the notion of variational measure with respect to a derivation basis in a topological measure space and consider a Kurzweil–Henstock-type integral related to this basis. We prove a version of Hake’s theorem in terms of a variational measure.
The Syllogistic with Unity
2011
We extend the language of the classical syllogisms with the sentence-forms “At most 1 p is a q” and “More than 1 p is a q”. We show that the resulting logic does not admit a finite set of syllogism-like rules whose associated derivation relation is sound and complete, even when reductio ad absurdum is allowed.
Dynamics of morphological processing in pre-school children with and without familial risk for dyslexia
2020
Difficulties in phonological processing and speech perception are associated with developmental dyslexia, but there is considerable diversity across people with developmental dyslexia (e.g., dyslexics with and without phonological difficulties). Phonological and morphological awareness are both known to play an important role in reading acquisition. Problems in morpho-phonological information processing could arguably be associated with developmental dyslexia, especially for Finnish, which is a rich morphologically language. We used MEG to study the connection between morpho-phonology in the Finnish language and familial risk for developmental dyslexia. We measured event-related fields (ERF…
Derivation and validation of a novel bleeding risk score for elderly patients with venous thromboembolism on extended anticoagulation
2017
SummaryExisting clinical scores do not perform well in predicting bleeding in elderly patients with acute venous thromboembolism (VTE). We sought to derive an easy-to-use clinical score to help physicians identify elderly patients with VTE who are at high-risk of bleeding during extended anticoagulation (>3 months). Our derivation sample included 743 patients aged ≥65 years with VTE who were enrolled in a prospective multicenter cohort study. All patients received extended anticoagulation with vitamin K antagonists. We derived our score using competing risk regression, with the time to a first major bleeding up to 36 months of extended anticoagulation as the outcome, and 17 candidate var…
